Polymer Macromolecular Network Design by Controlled Photopolymerization of Light-Sensitive Bio-Derived Building Blocks for UV- Light-Assisted 3D Printing Processing
29th IUPAC Symposium on Photochemistry 2024
Sergejs Gaidukovs, Anda Gromova, Maksims Jurinovs

The current presentation deals with the molecular network design of UV-light curable biobased polymeric resins. Synthetic reactions can convert rapeseed, linseed, and grapeseed oils into acrylate and epoxide monomers [1]. In addition, light-sensitive moieties such as acrylic groups can be incorporated into nanocellulose [2]. Controlled radical and cationic-initiated living polymerization can be chosen to regulate the formation of crosslinked polymer chain networks from these building blocks. Components can be selectively crosslinked to different extents by controlling the UV-light intensity and irradiation dose; it can be performed in situ during stereolithography or UV-light-assisted extrusion 3D printing.
